Did anyone make their own invitations?

I am beginning to think maybe I should do my own? One of my BM is the art director for Clairol's and she offered to design my invitations.... but she's a busy gal and I don't want to add more work on her plate...
I've been browsing and have not see anything I like.... so, I wanted to know if making them ourselves would be hard? I am not very artistic at all!
